Satellite imagery and machine learning used for the mapping of six seminatural open wetland types and land-use disturbance in European countries shows that wetlands are highly fragmented and have uneven restoration needs.
A molten salt, high-pressure synthesis method enables solution-based production of diverse refractory metal nitride nanocrystals, expanding access to technologically important nitride materials for advanced applications.
Gatos têm uma reputação não muito positiva. Aqui vai mais um sinal que talvez reforce isso: cientistas estão começando a achar que até mesmo um comportamento aparentemente inocente -lamber outro gato- pode não ser sempre algo gentil.

Until about 60,000 years ago, diminutive hominin cousins, Homo floresiensis (affectionately nicknamed Hobbits for obvious reasons), shared the island of Flores with Komodo dragons, pygmy elephants, and giant rats.
Based on the presence of hominin and pygmy elephant bones in the same layers of cave sediment, it originally looked like the Hobbits had hunted and butchered dwarf elephants—an impressive feat for such a tiny hominin. But according to University of Tübingen anthropologist Elizabeth Veatch and her colleagues, it was the Komodo dragons that were the hunters, while the Hobbits only showed up to scavenge what was left.
If Veatch and her colleagues are right, their findings may challenge some of the assumptions we’ve made about Homo floresiensis—and about which hominin species was the first to venture into the wider world beyond Africa.
